    • The CDM-570AL provides an L-Band IF frequency range from 950 to 2250 MHz. • The CDM-570A provides a 70/140 MHz IF frequency range from 50 to 90 MHz and 100 to 180 MHz. • The CDM-570AL consumes only 29 Watts (typical, without any option cards).

  • Page 42: Functional Description

    T1 and E1 and, when the modem is equipped with the optional Packet Processor, Ethernet. • The CDM-570A/570AL is compact – it is 1RU high, with a depth of 16 inches for the CDM-570AL, 11 inches for the CDMR-570AL Reduced Chassis Depth unit, and 13.13 inches for the CDM-570A.
  • Page 43 CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5 In the FEC encoder, the data is differentially encoded, scrambled, and then convolutionally encoded. Following the encoder, the data is fed to the transmit digital filters, which perform spectral shaping on the data signals. The resultant I and Q signals are then fed to the BPSK, QPSK/OQPSK, 8-PSK, or 16-QAM modulator.

    Be sure to take the following operational conditions into consideration when using CDM-570 Compatible Mode operation: 1. Use of CDM-570 Compatible Mode is required ONLY when the CDM-570A/570AL is a component in an existing network of CDM-570/570L modems. Otherwise, this mode should NOT be used, as it will make new (CDM-570A/570AL) features unavailable.

    CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5 8.4.1 Packet Structure The exchange of information is transmitted, Controller-to-Target and Target-to-Controller, in ‘packets’. Each packet contains a finite number of bytes consisting of printable ASCII characters, excluding ASCII code 127 (DELETE).

  • Page 270: Start Of Packet

    CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5 8.4.1.1 Start of Packet Controller-to-Target This is the character ‘<’ (ASCII code 60). Target-to-Controller This is the character ‘>’ (ASCII code 62). The ‘<’ and ‘>’ characters indicate the start of packet. They may not appear anywhere else within the body of the message.

From Controller-to-Target, the only permitted values are: Symbol Function The ‘=’ code is used as the Assignment Operator (AO). It establishes that the Instruction Code that precedes it is issued as a command (ASCII Code 61) to assign or configure operation.

    CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5 Symbol Function If a message is sent via a local modem to a distant-end device or ODU, the message was transmitted transparently through the local (ASCII Code 126) modem. In the event of the distant-end device not responding, the local modem wil generate a response.

The CDM-570A/570AL implements a Closed Network version of Rate 2/3 8-PSK/TCM/RS, using either the 220, 200 or 200,180 Reed-Solomon outer codes. Although not compatible, it provides identical performance to the Open Network IESS-310 standard.

    Turbo Codes have been developed, Turbo Convolutional Codes (TCC), and Turbo Product Codes (TPC, a block coding technique). Comtech EF Data has chosen to implement an FEC codec based on TPC. A Turbo Product Code is a 2 or 3 dimensional array of block codes.

    There are occasions where a user may wish to operate a satellite link with no forward error correction of any kind. For this reason, the CDM-570A/570AL offers this uncoded mode for three modulation types – BPSK, QPSK, and OQPSK. However, the user should be aware of some of the implications of using this approach.

    The transponder downlinks the composite signal containing both carriers on the same band to the CDM-570A/AL which then translates the signal to near baseband where it can be filtered (decimated) and then processed as a complex envelope signal. The CDM-570A/AL then suppresses the version of the near end carrier on the downlink side and then passes the desired carrier to the demodulator for normal processing.
